Melting of peridotite vs. eclogite
Isobaric melting of lherzolite
Compositional Change in Residue
Isotopes, Enrichment & Depletion
Magma composition vs. F, P, T
Stolper (1980) Peridotite melting at 1 atm to 2 GPa.

Oxide% variation in partial melts
Oxide variation as F
Eclogite melting
Effect of volatile phases on mantle solidus and melt composition
Eclogite+Liq field in the CMAS system at 3 GPa (Presnall)
